Teuthology docker 目标 hack (1/3)
teuthology 运行 任务 测试 Ceph 集成在 目标 上的情况，这些目标可以是虚拟机或裸机。 容器 hack 添加了对 docker 容器的支持，作为一种替代方案。
... 正在运行任务 exec... 执行自定义命令... 正在角色 mon.a 主机 container002 上运行 sudo 'TESTDIR=/home/ubuntu/cephtest' bash '-c' '/bin/true' 正在运行 docker exec container002 bash /tmp/tmp/tmptJ7hxa 持续时间为 0.088931 秒 ...
使用此 hack 的 worker 监听 容器 tube
$ mkdir /tmp/a /tmp/logs $ ./virtualenv/bin/teuthology-worker \ -l /tmp/logs --archive-dir /tmp/a \ --tube container
一个无操作任务

通过 容器 tube 调度
./virtualenv/bin/teuthology-schedule --name foo \ --worker container --owner loic@dachary.org \ noop.yaml 任务已使用名称 foo 和 ID 29 调度 2014-10-29 14:28:28,415.415 警告:teuthology.report:未在 /home/loic/.teuthology.yaml 中设置 results_server；无法报告结果
该实现依赖于 docker 1.3 docker exec 命令。它被用作对 ssh 连接的替代。

这些容器已添加到 paddles 数据库，使用了新的 is_container 字段。
for id in 1 2 3 ; do sqlite3 dev.db "insert into nodes (id,name,machine_type,is_container,is_vm,locked,up) values ($id, 'container00$id', 'container', 1, 0, 0, 1);" done
它们没有预先配置，因为它们是按需创建的。由于 docker 提供了一个镜像仓库，因此不使用 downburst。
